MLB Strikeout Props Today August 20th, 2026: Best Pitcher K Picks, Predictions & Odds

Thursday's card is topped by one of the American League's most quietly dominant arms, a returning Tommy John success story finding his groove, and a pair of pitchers attacking lineups that rank among the more strikeout-prone units in baseball right now. The board leans heavily toward the over across the board today, with real matchup and form data backing up every selection. The fade of the day involves a strong left-hander running into a division rival that has been hot and disciplined at the plate lately.

Let's get into today's best MLB strikeout picks.

Best MLB Strikeout Props Today

Gavin Williams Over 7.5 Strikeouts (+115)

Williams has quietly become one of the American League's more effective starters, backing 190 strikeouts and 11 wins across 149 innings with a 31.8 percent strikeout rate and 11.5 K/9 that both rank among the better marks in baseball. He is averaging 8.7 strikeouts across his last ten outings, and eight would actually sit slightly below that recent pace rather than represent a reach. San Francisco has struggled to generate consistent offense of late, batting just .213 with only seven homers over its past ten games, a lineup that has had trouble doing much of anything against quality pitching. His deep four-pitch arsenal and the expectation of facing roughly 24 batters give him a real path to clearing this number even with some hard-hit-ball risk baked into his profile. Lock it in.

Robert Gasser Over 5.5 Strikeouts (+128)

Gasser has settled in nicely after a rocky first start following the All-Star break, posting a 3.33 ERA and a 1.19 WHIP across his last five outings covering 27 innings. His strikeout stuff has come along with that improved form, and he gets a Seattle lineup that carries a 23.8 percent strikeout rate against left-handed pitching, a solid matchup for a pitcher trending in the right direction. Milwaukee has been red-hot as a team heading into this series, giving Gasser plenty of run support and a longer leash to work with on the mound. That combination of improving form and a favorable opponent gives him a genuine path to clearing this modest number. Get it in.

Kyle Bradish Over 5.5 Strikeouts (-135)

Bradish has settled into a groove since returning from Tommy John surgery, posting a 3.65 ERA with 8.4 strikeouts per nine innings across 24 starts this season. His last outing produced six innings and just two earned runs against Tampa Bay, continuing a stretch of quality starts that has stabilized Baltimore's rotation down the stretch. New York carries a 25.1 percent strikeout rate against right-handed pitching, one of the more favorable matchups on today's board for a pitcher who has already shown he can miss bats at a high level in his return season. That combination of a strong recent form and a strikeout-prone opponent makes this number very reachable. Lock it in.

Peter Lambert Over 5.5 Strikeouts (-102)

Lambert has been the model of consistency for the better part of two months, allowing two earned runs or fewer in eight straight starts while working at least five innings in every one of them. His 117 strikeouts this season have come with just 15 walks over his last 44.1 innings, a strikeout-to-walk profile that reflects real command and swing-and-miss ability together. The Angels check in with the second-highest strikeout rate in baseball against a right-hander today, an extreme matchup edge that plays directly into Lambert's continued success. That blend of sustained excellence and a premium strikeout environment gives him a clear path to clearing this number. Take it.

Pitcher Strikeout Projections vs Betting Lines

Betting lines move for a reason, and our job is to find where the market has not fully priced in a matchup edge. That is the foundation of every pick you see above.

Strikeout Props to Avoid Today

Ian Seymour vs Toronto Blue Jays

Seymour has been excellent this season, backing 115 strikeouts and a 28.8 percent strikeout rate that ranks among the better marks in the American League. The complete picture points elsewhere tonight, though, since Toronto's strikeout rate against left-handed pitching has dipped to just 16.9 percent over the last two weeks, a notable drop from an already modest season-long mark. The Blue Jays have also been playing their best baseball of the stretch run, going 7-3 over their last ten games while sitting just a game back of a wild-card spot, and a hot, disciplined lineup tends to put the ball in play rather than chase. Even a pitcher with Seymour's swing-and-miss ability can run into trouble against an opponent that is both hitting well and simply not striking out much right now. Leave it alone.
